摘要： 提出一种基于同步数据触发结构(SDTA)的密码处理技术。利用SDTA的高并行、广谱适应和多态易用等特点，满足密码处理的高性能、强适应性和抗攻击性等要求。基于该结构的设计优化流程进行应用分析，得出瓶颈操作，通过设计相应的计算加速单元实现应用加速，且新单元可以方便地加入该结构内核中，从而减少处理器的设计时间。

Abstract: This paper proposes a kind of cipher processing technology based on Synchronous Data Triggered Architecture(SDTA), which makes use of the characteristics of SDTA such as high parallelism, high adaptability and polymorphism to meet the demands of high performance, strong adaptability and anti-attacking. Its design and optimization flow is used to analyze the applications to get the bottleneck operations, and the corresponding processing units are designed to accelerate the specific applications. The new designed units are easy to be added to the SDTA core, which helps to reduce the design time.

Key words: cipher processing, Synchronous Data Triggered Architecture(SDTA, design flow, heterogeneous multi-core
